Abstract
PURPOSE: To evaluate whether traversal through the central part of a pulmonary lesion by a biopsy needle, and other factors, increases the risk of hemoptysis in patients undergoing CT-guided percutaneous transthoracic needle biopsy (PTNB). MATERIALS AND METHODS: From July 2012 to November 2016, 227 patients undergoing 233 procedures were recruited as our study population. Patients were classified according to the occurrence of hemoptysis. Radiological assessments were performed by reviewing multiplanar reconstructed CT images. Other factors complicating PTNB-related hemoptysis were classified into (1) patient-related variables: age, gender, presence of emphysema; (2) lesion-related variables: size, location, distance to pleura, characteristics, presence of and degree of enhancement, histopathology of biopsy results; and (3) procedure-related variables: lesion depth, patient's body position. RESULTS: Twenty-two cases (9.4%) experienced hemoptysis. Univariate analysis revealed that subsolid lesions (p = 0.031) and lesion depth > 1 cm (p = 0.049) were risk factors. Traversal through the central part of the lesion by the biopsy needle was not a risk factor. CONCLUSION: Traversal through the central part of the lesion by the biopsy needle is not a risk factor of PTNB-related hemoptysis, but subsolid lesions and lesion depth > 1 cm increase the risk of hemoptysis.
